Understanding Car Start/Stop Technology: How It Works and Its Benefits

Two technologies—remote starters and in-car start/stop systems—are both designed to optimize the way your vehicle functions, each in a different manner. Remote starters are useful for enhancing convenience and security, while in-car start/stop systems help in saving fuel and reducing emissions. This article will delve deeper into the mechanics and benefits of these technologies.

Remote Starters: Simplifying the Start/Stop Process

Essentially, a remote starter is a device that allows you to start your car from a short distance away through a handheld transmitter or a smartphone application. The key aspect of a remote start is that it operates by simulating the circuit that is activated when you insert a key or push the start button. In other words, the remote direct the car to complete an electrical circuit, just as if you were physically inside the vehicle.

The system works through a sophisticated control module that is connected to the ignition switch and other starter controls. When you initiate a remote start command, the signal is received by a receiver, which then sends the necessary power to the mechanisms that need it to start the car. For vehicles that require a key to start, you press the brake (which places the vehicle in a ‘park’ or ‘off’ state), and then you can use the key to start the engine. Security-wise, if your vehicle requires a fob to start, a remote start system can bypass this requirement but still needs a fob to move the vehicle.

Car Start/Stop Technology: Fuel and Emissions Savings

When it comes to the smaller, more frequent stops, like at traffic lights, a car start/stop system comes into play. This technology can significantly reduce the amount of time the engine spends idling, thus saving fuel and reducing emissions. By automatically shutting down and restarting the engine, it helps in optimizing fuel consumption, particularly for vehicles that spend a lot of time in stop-and-go traffic.

Here’s how it works: When you come to a complete stop, such as at a red light, the car’s electronics detect that the vehicle has stopped. At this point, the engine switches off to save fuel. When you are ready to move again, the system restarts the engine instantly as you press the clutch (for manual transmissions) or the brake (for automatic transmissions).

Technical Details and Adaptations

The start-stop system is designed to work seamlessly with a variety of accessories and systems that require power from the engine. In older vehicles, accessories such as compressors and water pumps are often driven by a serpentine belt attached to the engine. With the engine shutting down, a more sophisticated design is required to keep these systems running. The common solution has been to use electric motors to power these devices, as the system must be able to function even when the engine is off.

One prime example of this technology in action can be observed with the Honda PCX 125cc scooter, which has featured start-stop technology in Asian markets for a decade. When released in Europe, the PCX 125cc came equipped with this technology, whereas its North American counterpart did not.

For vehicles with manual transmissions, the process of activating the start-stop feature is quite straightforward: you need to stop the car, press the clutch, move the gear lever to neutral, release the clutch, and then the engine will shut off. However, it is important to note that the engine will not stop if the car is in motion even if the steps are followed. The engine will automatically restart when the clutch is pressed before you select a gear to move the car. The system may also restart if there is a demand for power from accessories like the air conditioning system.

Conclusion

Start/stop systems and remote starters both offer significant benefits and conveniences. Remote starters provide peace of mind and ease of access, especially in cold weather or at remote locations, while in-car start/stop systems contribute to environmental friendliness and better fuel efficiency. Understanding how these systems work can help you make informed decisions about your vehicle and its maintenance needs.
